Duck boat accident in Boston injures six people near Charles River entrance Saturday

An amphibious sightseeing vehicle capsized Saturday near the Charles River boat ramp in Cambridge, Massachusetts, leaving six people injured in an incident that prompted a swift emergency response from multiple agencies. The vessel, operated by Boston Duck Tours, tipped onto its side at the water entrance, though all passengers remained out of the river, according to state police officials. Two individuals sustained injuries classified as serious, while four others suffered minor harm.

The Cambridge Police Department confirmed that everyone aboard the vehicle has been accounted for following the accident. Emergency crews from the Massachusetts State Police Marine Unit, Cambridge police, and local fire departments converged on the scene to assist the injured passengers and secure the overturned craft.

Emergency response mobilized as vessel tips at boat ramp

State police troopers arrived alongside marine specialists to manage the rescue operation near the Cambridge boat ramp entrance. Fire officials worked to extract passengers from the tilted amphibious vehicle while paramedics assessed injuries on site. The fact that no one entered the water significantly reduced the severity of the incident, though the two serious injuries required immediate medical attention and transport to area hospitals.

The Cambridge Fire Department coordinated with state authorities to stabilize the vessel and prevent further complications. Witnesses reported seeing the distinctive vehicle, designed to operate both on land and water, lose stability as it approached the river transition point.

Investigation launched into cause of amphibious vehicle overturn

Massachusetts State Police will lead the investigation into what caused the World War II-style amphibious vehicle to capsize. The agency assumed primary jurisdiction because the incident occurred directly at the Charles River entrance, placing it under state waterway authority. Investigators will examine multiple factors that could have contributed to the accident:

  • Mechanical failure or maintenance issues with the amphibious vehicle
  • Weight distribution and passenger loading procedures
  • Operator error or navigation misjudgment at the ramp transition
  • Environmental conditions including water currents and ramp conditions
  • Compliance with safety protocols and equipment standards

Authorities have not yet released preliminary findings, and the timeline for completing the investigation remains unclear. The overturned duck boat was secured at the scene while forensic examination begins.

Boston Duck Tours operates fleet of replica military vehicles

The vehicle involved is part of the Boston Duck Tours fleet, which has operated historical sightseeing excursions throughout the city for more than three decades. These tours combine land-based routes through Boston’s historic neighborhoods with aquatic segments along the Charles River, using restored amphibious vehicles modeled after WWII military transports. The distinctive yellow and green vehicles have become iconic fixtures of the city’s tourist landscape, carrying thousands of visitors annually through downtown streets before entering the water.

Boston Duck Tours has built a reputation as a city institution, offering narrated tours that highlight Revolutionary War sites, architectural landmarks, and waterfront views. The company has not yet issued a public statement regarding Saturday’s accident or addressed questions about vehicle maintenance records and safety procedures. Requests for comment from the tour operator went unanswered as of Saturday evening.

Duck boats celebrated in championship parades across Boston sports

Beyond their tourism function, these amphibious vehicles have gained cultural significance in the Boston area through their role in championship victory parades. The duck boats have transported the New England Patriots through the city streets six times following Super Bowl victories, carried the Boston Red Sox four times after World Series wins, and celebrated championships with the Boston Celtics twice and the Boston Bruins in 2011. These parade appearances have embedded the vehicles into local sports culture and collective memory.

The celebratory associations contrast sharply with Saturday’s accident, which marks a serious safety incident for the touring company. Previous duck boat accidents in other cities have raised questions about the safety of these vintage military vehicles in civilian tourism applications, though Boston’s fleet has maintained relatively few publicized incidents over its operational history.

As investigators work to determine what caused Saturday’s capsizing, the condition of the two seriously injured passengers remains a priority for medical teams. The incident serves as a reminder of the inherent risks in operating amphibious vehicles that must transition between road and water environments, particularly at boat ramps where changing conditions can affect stability. State police are expected to release additional information as the investigation progresses in the coming days.
